This is the compilation and countdown of top best 20 government, presidential, royal, sultan, emir planes. The prices are CCA mostly because I couldn't get prices, except for some. So I used the prices this jets would cost new and for commercial use. Jets include Airbus A340, A330, A380, Boeing 777, 747 and Ilyushin-96.
Governments, countries: Egypt, Libya, Russia, France, Sri Lanka, Germany, Tunisia, Algeria, Jordan, Bangladesh, Yemen, Oman, S Korea, Brunei, Bahrain, Japan, Kuwait, Saudi Arabia and USA.
I only counted the planes that are owned by governments and not ones, that are occasionally lend to them by airlines.
